https://notcve.org/view.php?id=CVE-2023-20569
08 Aug 2023 — A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the return address prediction. This may result in speculative execution at an attacker-controlled address, potentially leading to information disclosure. Una vulnerabilidad de canal lateral en algunas de las CPU de AMD puede permitir que un atacante influya en la predicción de la dirección de retorno. Esto puede dar lugar a una ejecución especulativa en una dirección controlada por el atacante, lo que podría conducir a l... • http://www.openwall.com/lists/oss-security/2023/08/08/4 • CWE-203: Observable Discrepancy •
